What is NMN, and what is it supposed to do?
NMN is one of the most talked-about "longevity" supplements. Here's the grounded version of what it is.
The basics
- NMN is a precursor to NAD+ (nicotinamide adenine dinucleotide), a coenzyme involved in energy production and DNA/cellular repair.
- NAD+ levels decline with age, which is why supplementing precursors like NMN has drawn interest.
- Most evidence so far is from cell and animal studies; human trials are growing but still preliminary.
Community members are candid that NMN is an area of active research rather than settled science — one widely-read r/NMN post is literally a doctor-reviewed list of the "top 7 myths." Treat NMN as a supplement you might explore for general wellness, keep expectations realistic, and read the safety note below.
